Bests & Worsts Reviews from Amazon

I was pleased with my previous order of this product so ordered again. However, this time I noticed that the powder was clumpy when put in my drink. I went back to look at my first order and saw they included an experiation date of July 2019. The second purchase did not have an expiration date so I believe I was sent an expired product and it has gone bad. I've included pictures of both packages for proof - Very disappointed!
